ROLLER-BEARING HINGE.

SPECIFICATION forming part of Letters Patent No. 564,055, dated July 14,1896.

Application filed February 26, 1896- Serial No. 580,864. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM H. DIoKE and AUGUST H. GAERTNER, of thecity of St. Louis, State of Missouri, have invented certain new anduseful Improvements in a Roller- Bearing Hinge, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

Our invention relates to an improved rollerbearing hinge; and itconsists in the novel construction, combination, and arrangement ofparts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of our improvedroller-bearing hinge when in position for use, the door and frame beingbroken away. Fig. 2 is a top plan view of the parts shown in Fig. 1.Fig. 3 is a perspective of the roller and its connection of which wemake use. Fig. 4 is a side elevation of one half of the hinge, and Fig.5 is a side elevation of the other half. Fig. 6 is a top plan view ofthe part shown in Fig. 4, and

gig. 7 is a top plan view of the part shown in Referring by numerals tothe accompanying drawings, 1 and 2 represent the parts to be hingedtogether. for use where the swinging portion occupies approximately aperpendicular position, and especially on heavy gates and doors.

For convenience and uniformity of description we will designate l as thepost and 2 as the door. The part 3 of the hinge is screwed to the post,and the part 4 is screwed to the door in the ordinary manner. In actualoperation the hinge might as well be turned over and have the part 4screwed to the post and the part 3 screwed to the door. -A hinge pin,comprising the head 5 and the neck 6, is attached to the part 3, asshown in Fig. 4. Formed on the part 3 and extending radially therefromis a stop 7. Formed on the part 3 concentric with the axis of the saidhinge-pin is an inclined surface 8, extending from the ridge 9 to saidstop 7, describing approximately a quarter of a circle. The part 4 has avertical aperture 10, designed to fit loosely v on the head of thehinge-pin 5. 'Formed on the part 4 and extending radially from said Ourhinge is designed aperture'is a stop 11, similar to the stop 7. Formedon said part 4, concentric with said aperture and extending from theridge 12 to saidstop, is an inclined surface 13, similar to the inclinedsurface 8.

A length of wire 14, bent into a loop, has a roller 15 rotatably mountedupon one end, said wire being headed to hold the roller in position, asshown in Fig. 3, and said loop is mounted upon the neck 6 of thehinge-pin, as shown in Fig. 1. When placed in proper position, theroller 15 operates between the inclined surfaces 8 and 13, as shown inFig. 1.

In the practical operation of our device the weight of the door 2 restsupon the roller 15 and is held in position by the hinge-pin 5. When thedoor is shut, the roller 15 rests against the stop 7, and the stop 11rests against the top of said roller. When the door is opened, theroller 15 climbs the inclined surface 8, and the inclined surface 13climbs the roller, thus raising the door above its normal position. Whenthe door is released, the weight will cause the roller to run down theinclined plane 8 to its normal position against the stop 7. 7

By the use of our hinge the door becomes self-closing. Theroller-bearing in the hinge will make it easier to operate than the olddevices, and the hinge is simple and durable in construction.

We claim- In a hinge, the two mating parts 3 and 4, the'hinge-pin fixedin one of said parts, said hinge-pin comprising the head 5 and the neck6, the opposite. part from the one to which the hinge-pin is fixedhaving a vertical aperture designed to receive said hinge-pin, the wireloop 14 surrounding the neck 6 of said hingepin, and the roller 15rotatably mounted upon the outer end of said wire and between the facesof said parts 3 and 4, substantially as herein specified.

In testimony whereof we afiix our signatures in presence of twowitnesses.
